Katsuki Bakugo

Katsuki Bakugo, also known as Kacchan by his childhood friends, and his hero name Great Explosion Murder God Dynamight, is a student in Class 1-A at U.A. High School, training to become a Pro Hero. He is the deuteragonist of the series. Katsuki has proven to be one of the strongest students in Class 1-A, earning third place in the Quirk Apprehension Test, while placing first in both the U.A. Entrance Exam, having the most villain points, and the U.A. Sports Festival. Katsuki's fighting style is an all-out offense, using his Quirk's propulsive abilities to close the distance between him and his opponents, followed by a bombardment of close-range attacks that often start with a powerful right hook. Katsuki is able to use his Explosion to propel himself through mid-air, blind opponents, and release long-range blasts, among other applications.

Explosion is a versatile Quirk, especially for battle situations, as the recoil caused by the blasts can be exploited by Katsuki for mobility purposes. During the U.S.J. Incident, Katsuki was able to single-handedly overpower and immobilize Kurogiri, a highly capable villain. At the U.A. Sports Festival, he was able to defeat Fumikage Tokoyami and Shoto Todoroki, who were considered the two other strongest students in Class 1-A at that point. Many notable Pro Heroes, such as Shota Aizawa and All Might, have praised Katsuki's prowess, noting the sheer amount of potential he carries. The League of Villains also took notice of Katsuki's strength and went as far as trying to kidnap him so he could be converted to their cause, even if it meant sacrificing members of the Vanguard Action Squad as his potential membership would have far exceeded the risk. Katsuki is strong enough to fight toe-to-toe and even overpower Izuku when he's using 5% of One For All. During the Joint Training Arc, Katsuki displayed that, despite the cold weather conditions of the winter season weakening his Quirk, he can still fight efficiently. Katsuki has also become slightly less insubordinate when paired with people and has developed a degree of camaraderie, as he utilizes his abilities to repel opponents that overpower his comrades. Not willing to let Izuku get ahead of him and never taking his intended goal of surpassing All Might lightly, Katsuki is always building up his power, improving his technique and looking forward to knowing what he is not able to do right now, with the intent of being able to do so in the future. Katsuki's unstoppable drive to win is perhaps his biggest strength, with all of his classmates, including Izuku, having faith in his ability to earn victories. By the time of the Paranormal Liberation Raid, Katsuki's overall abilities and proficiency have significantly increased, and he's even able to match the speed of Izuku using One For All at 30%. Katsuki's Quirk allows him to secrete nitroglycerin-like sweat from the palms of his hands and ignite it on command, allowing him to create strong explosions. The more Katsuki sweats, the stronger his explosions become. If Katsuki overuses this power, his forearms will start to ache. Katsuki has a strong grasp on the applications of his Quirk, something that was acknowledged by Best Jeanist, a top Pro Hero; not only can Katsuki use the explosions for attacking, he can also use them to propel himself and navigate through the air at high speeds, allowing him to fly at his opponents without giving them time to react, as well as evade incoming attacks, even while in the air. The shockwave from an explosion can even be used as a shield. Katsuki can keep up his explosions continuously, long enough to break through Eijiro's hardening Quirk and negate Shoto's "Heaven-Piercing Ice Wall" for a short while before being overwhelmed. As part of his training, Katsuki submerged his hands into boiling water to expand his sweat glands, then created chain explosions toward the sky to increase the scale of his attacks.
